Hello - I’m gathering arguments. In your opinion, what are the arguments in favour of using boot over leiningen ?

What might cause this type of stacktrace in ClojureScript application?

@pandeiro you maintain some docker images we use — I’d like to know your stance regarding boot<>lein. Which do you prefer and why ?

Has anyone else ever had this problem with boot-cljs-test?

Running cljs tests...

It used to work.. I think 😛

Oh it looks that the 404 is not a problem

@olegakbarov that looks like an issue with FSEvents, the system file watching protocls

which OS are you on?

This was a false alarm.. Ignore me

@mitchelkuijpers 🙂

@micha im on macOS; this came up when i was trying to add some js externals https://github.com/alesguzik/cljs-npm-bundle

any chance node_modules folder can cause this type of issues?

@olegakbarov those are just log messages, right?

it's not actually causing a failure?

no, it fails

there is a limitation of FSEvents on OSX, you can only have a certain number of watched nodes

if your node_modules contains tens of thousands of files and directories it could be an issue

@olegakbarov reference https://github.com/gruntjs/grunt-contrib-watch/issues/75

yeah, that looks very much like this

Hi @pseud - I still use both, since some projects I work on use lein, but if I am starting a project from scratch, I use boot.

My lein docker image probably needs updating; I just updated the boot one to use the alpine-based java image, reducing it by about 500MB

hey y’all is there any way to have boot automatically use the clojure version set by set-env!? I get that boot has to already load a clojure version before reading set-env… but is there some magic I don’t know about?

@nonrecursive the usual way is to make a boot.properties file in the project that has the same version as what you use in set-env!

that will override your global preferences in ~/.boot/boot.properties

additionally, sometimes you want to go the other way, like you don't care which version of clojure you use, but you want to have some clojure dependency in your env because of maven

in that case i do (set-env! :dependencies [['org.clojure/clojure (clojure-version)]])

so if you have a project you can make a boot.properties file with BOOT_CLOJURE_VERSION=1.8.0 or whatever

then in your :dependencies you can put ['org.clojure/clojure (clojure-version)]

sweet that’s what I was looking for 😍

that will allow you to set the version of clojure in one place, the boot.properties file

thanks man

miss you 😘

how's the life man?

are there instructions somewhere for creating/using the secring.gpg that boot build-jar push-release asks for now?

i don't have an existing keypair, i guess i can just create a new one and that's that...

@pandeiro there should be info in the wiki about it, i think?

Thanks @micha, I'll check that out

I don't see ~/.gnupg/secring.gpg referenced here: https://github.com/boot-clj/boot/wiki/Repository-Credentials-and-Deploying

looking at bootlaces, it seems like it hardcodes that path and passes it to push

I'll just create that file in that location, but I'm not sure exactly what it is

@pandeiro ooh, alpine works for java now? That's awesome. I lost a limb trying to get that working a few months ago.

@dominicm yeah if you docker pull pandeiro/boot:latest, it's just 150MB, which is great

@dominicm @pandeiro I confirm as I have a docker app on ECS that works like a charm

150MB is exactly how big it should be. The size of some images is truly appalling.

I have used develar/java:8u45 though

@richiardiandrea there's also this: https://hub.docker.com/_/openjdk/ (not sure if you specifically want the oracle jdk)

oh thanks that's great, at the time it was the only one I found

Hmm, I guess my keyring troubles might be due to the GnuPG 2.1 format... I only have a pubring.kbx in my ~/.gnupg dir

ah yes that changed stuff

I actually haven't deployed using gpg and boot in a while

me neither 😕 -- i'm trying to do some long, long overdue maintenance on boot-http

oh man thanks! 😄

yes! apologies!

let me see the wiki page

i haven't used clojure at all in the last 6 months, sad stuff

I have concluded as well my last Clojure adventure and looking for new stuff, but let me see first if I can help you with that

@pandeiro so which step is not working, it looks like the wiki procedure abstracts over gpg details (call to gpg-decrypt)

if you set gpg2 shouldn't it work?

yeah, it is the push-release step

I mean export BOOT_GPG_COMAND=gpg2

same error, still no such file

and there isn't... i guess i just need to understand how the pubring.kbx etc in my .gnupg map to pubring.gpg / secring.gpg

mmm...but that's what I am saying, if you created a new keypair gpg2 should read it from there, unless push-release explicitely reads the .gnupg folder, which is probably not desirable, I am checking the code

yeah it does

oh that's why

mmm where...I can't see it https://github.com/adzerk-oss/bootlaces/blob/master/src/adzerk/bootlaces.clj

i think it is in the built-in push task itself

checking

nope, it looks like there's nothing referring to that https://github.com/boot-clj/boot/blob/ac835cea8c18e926bb843e01579b86e3f30458d2/boot/pod/src/boot/gpg.clj

in a repl, I would try to double check that this line: https://github.com/boot-clj/boot/blob/ac835cea8c18e926bb843e01579b86e3f30458d2/boot/pod/src/boot/gpg.clj

gives you gpg2

or you can alias gpg with gpg2 if it is not already done

i tried exporting the environment variable and i'm pretty sure gpg2 was used

there is this: https://github.com/boot-clj/boot/blob/master/boot/core/src/boot/task/built_in.clj#L929

but it isn't referenced anywhere (?)

yes it looks like it is not used

(maybe some old stuff)

@pandero which version are you using? have you tried 2.7.0-rc1?

No, but I think I may have fixed it by exporting the secret key to that filepath

I did gpg --export-secret-keys > ~/.gnupg/secring.gpg -- that at least produced a different error when I tried to push 😉

lol but I would try the new version, look, that param has been deprecated as you don't usually need it explicitely: https://github.com/boot-clj/boot/blob/ac835cea8c18e926bb843e01579b86e3f30458d2/doc/boot.task.built-in.md#push

OK, I will try that out

But otherwise, it seems to have worked: https://clojars.org/pandeiro/boot-http

Thanks for the help @richiardiandrea !

oh cool no problem !

Has anyone increased the available heap with -Xmx= on windows for 'boot dev'? Tried the boot.l4j.ini. no dice.

I set this in my .bashrc: export BOOT_JVM_OPTIONS="-Xmx1g -client -XX:+TieredCompilation -XX:TieredStopAtLevel=1 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -Xverify:none -XX:-OmitStackTraceInFastThrow"

@symbit ^

there should be a section in the wiki though

@richiardiandrea you're using cygwin bash on windows?

ah sorry windows

no sorry I don't use windows, I misread that 😉

hey, so I’m trying to get going with boot as a complete newbie but long-time lein user, and I am having trouble figuring out how to simply do the equivalent of lein new <project-name> so I can get something to specify dependencies and futz around to test out a project-specific repl. The docs make it seem as though I will have to write a bunch of code to get this outcome. Is that the case, or am I missing something obvious?

@ddellacosta You can use this https://github.com/seancorfield/boot-new

boot -d seancorfield/boot-new new -t app -n myapp

@kenny thanks. So that is not baked into boot huh?

Not yet. I believe there was a discussion about adding it in. Not sure where that conversation went though.

also, those flags, are those boot args or boot-new args? I’m assuming that they are boot-new args as boot doesn’t seem to have -n but I’m not sure I understand where boot ends and boot-new begins

the -d is an option to boot

-d is a boot arg which adds seancorfield/boot-new as a dependency. new is the task name (from boot-new) and everything after new is args & options to the new task.

I see, thanks @micha and @kenny

okay, next set of questions. I want to play with spec, so I tweaked the default set-env! call’s :dependencies value which boot-new created to look like this:

4│  (set-env! :resource-paths #{"resources" "src"}
  5│            :source-paths   #{"test"}
  6│            :dependencies   '[#_[org.clojure/clojure "RELEASE"]
  7│                              [org.clojure/clojure "1.9.0-alpha13"]
  8│                              [adzerk/boot-test "RELEASE" :scope “test”]])

however, when starting up a repl via cider-jack in Emacs, I get

3│  boot.user> *clojure-version*
  4│  {:major 1, :minor 7, :incremental 0, :qualifier nil}

so what am I not understanding now about how boot works?

(also, 1.7 ??)

wouldn’t it be cider-jack-in-clojurescript ?

@pseud I don’t know, would it?

I haven’t done any boot work with cider yet, really. But I recall with lein that cider-jack-in got me into my clojure repl and cider-jack-in-clojurescript booted a clojure-process which fired up figwheel. I’d imagine ‘cider-jack-in’ attempts to start something like “boot repl"

Don't know anything about cider + boot but if you are starting a REPL with boot repl then you will need to add a boot.properties file with

BOOT_CLOJURE_VERSION=1.9.0-alpha14

@pseud I just want a vanilla repl w/clojure 1.9 @kenny Okay, I can do that—but I’m specifically curious why my dependency didn’t get picked up.

Oh snap, forget about me. I’m tired. 🙂 Yes, you need a boot.properties file in the project.. boot -V > boot.properties and then update the version number of clojure. Otherwise you’ll get 1.7.0

@ddellacosta boot needs to run your build.boot file etc in clojure

so the version of clojure needs to be chosen before your code runs

@micha I guess there is a way to hook up cider so it does this by default, but it doesn’t out of the box huh?

oh, I see—so the set-env! won’t work in the case of clojure regardless based on what you’re saying @micha

I see

that's what ~/.boot/boot.properties can help you with

or ./boot.properties

Not sure if it’s the answer exactly but. It’s my understanding that lein fires up its own process, then spawns another JVM process for your project (unless you use trampoline) — that would allow lein to start with one version of clojure, and your program to use another. My understanding is that boot starts up a single JVM process and hands off control to your app — hence whatever clojure version mentioned in your boot.properties file will be what you’ll eventually get. But maybe I’ve misunderstood

okay, thanks @pseud and @micha and @kenny

think I can figure it out from here

yep that's right

you can, however, run differetn versions of clojure in "pods"

okay, I will put that in the list of something to look into once I’ve got the basics down 😄

similar to starting a separate jvm, but it's all in the same process

ddellacosta: hang in there.. Boot ends up being so much more convenient, I promise 🙂

similar to starting a separate jvm, but it's all in the same process

So after about 20 minutes I can already say, for the record, that it may be useful to have a bit more of a comprehensive “coming from leiningen? Start here…” tutorial somewhere. This doesn’t cut it: https://github.com/boot-clj/boot/wiki/Boot-for-Leiningen-Users

That’s not a comment on boot, as I don’t know enough about it yet to comment

but it has been pretty un-intuitive to get going from the path I thought was the most obvious, coming from lein

which I imagine most users will be…but perhaps not.

Again, this isn’t going to deter me from using boot—I’m not criticizing it in any way, just the lack of docs for my specific path in

I hope it’s clear I mean that very much constructively!

that wiki isn't really supposed to be a getting started type thing

Gotcha. My path in was http://boot-clj.com/ click on “get started” -> https://github.com/boot-clj/boot#install -> “huh how do I create a project” (then, maybe this leiningen entry in the wiki will help?)

@ddellacosta Could be true. I moved to boot because I had some issues while wanting to develop a library while developing an example which used it - something you’ll need “checkout dependencies” for in lein which is hell. Anyway, I didn’t really consult the lein migration page, but instead found a few blog posts which explained how boot tasks worked, how each task is self-documenting (`boot <task> -h`) and how they could be composed and how the deftask form worked. From there, I never looked back. TL;DR - there’s some good blogs providing quick overviews of how boot works 🙂

Ah, okay.

@micha @alandipert just watched this talk from david nolen and he mentioned cognitect uses boot too https://youtu.be/mty0RwkPmE8?t=3052
